' LIQUID FUEL COMBUSTION CHAMBER Filed Jan. 30, 1950 Patented June 16, 1953 LIQUID FUEL COMBUSTION CHAMBER Alfred Huyton, Burnley, England, assignor to Joseph Lucas Limited, Birmingham, England Application January 30 1950, Serial No. 141,186 In Great Britain February 2, 1949 1 Claim.

This invention relates to liquid fuel combustion chambers of the kind constructed from substantially cylindrical sheet metal sections having overlapping ends which are secured together by welding or otherwise, such chambers being intended for use, more particularly with jet-propulsion engines, gas turbines, or like prime movers.

The object of the invention is to provide an improved construction of the connections between one or more pairs of sections.

In the accompanying drawing:

Figure 1 is a sectional side elevation of a portion of a combustion chamber embodying the invention, Figure 2 is a cross section on the line 22 Figure 1, and

Figure 3 is a fragmentary section taken on the line 33 of Figure 1.

Referring to the drawing, the end of the section a, which is requiredto be inserted in the adjacent end of the next section b, has formed thereon an expanded short cylindrical portion 2 annular arrangement of closely adjacent air channels 9 through which cooling air can flow from a surrounding air jacket h into the sections. By this invention the interconnection of the adjacent ends of a pair of sections, and the provision of means whereby cooling-air can enter such that its outer surface can make close contact with the inner surface of the section b, the main part of the section a being of smaller diameter than the section 1;. Immediately adjacent cured together by electrical spot welding, or

otherwise, of the extremity of the one section to the other.

The construction above described provides an the sections is effected in a very simple and convenient manner. 1

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: A liquid fuel combustion chamber comprising at least two substantially cylindrical sheet metal sections, of different diameters, an expanded end integral with the smaller of the two sections having a continuous cylindrical periphery fitted closely within and secured to one end of the other section, a circumferential row of narrow slots immediately adjacent to the expanded end, a second circumferential row of narrow slots spaced from the first mentioned row, the slots in the said second row being situated in staggered relationship to the first row, and the metal of the section intermediate the two rows of slots being pressed outwardly at intervals to constitute an annular arrangement of closely adjacent air channels leading from the exterior to the interior of the slotted section.

ALFRED HUYTON.
